How Should a Tennis Bracelet Clasp Be? Safety Latch and Flexible Links
A tennis bracelet moves all day. The clasp and the links decide its lifespan as much as the stones do.
Box clasp and safety latch
The most common clasp on a tennis bracelet is the box clasp: the tongue slides into the box and is held by spring pressure. A box clasp alone is not enough; there should also be a second closure, a safety latch, that stops the clasp from opening by itself. On the sample, check that the latch closes firmly and stays in place when the clasp is fastened.
Links should be flexible
To sit comfortably on the wrist, the links need to flex along one line, not catch when turned, and keep the stones in an even row on the surface. Stones are matched by size and colour, and this matching defines how the bracelet looks.
Choice of metal and stone
14K or 18K gold is preferred for the strength of the clasp and links. The stones can be lab-grown diamonds or natural diamonds; the same design is made with either. Silver is also possible, but keep in mind that on a piece worn often the clasp needs fine workmanship.
What to check on the sample
- Does the clasp open and close repeatedly without trouble
- Does the latch stay fixed in the closed position
- Do the links move with the wrist without catching
- Are there any sharp points on the stone prongs
